GLEN r. Hitman, or senr LAKE-CIN, Filiali j GYLINQEB Y Application filed April 11,

My invention relates to all types of internal combustion engines in which pistons are operated within cylinders and has for its object to provide a new and eflicient cylinder l for said engine which,v mayV be renewed or changed to take up the wear which comes in all engines after continued use.

A further object of my invention is to provide a. new and economically constructed cylinder which may be reversed within the motor block or which may be turned or -rotated partially or completely to take up the wear of continued service.

A still further obj ect is to provide a cylinder for internal combustion engines which may be located within the cylinder block but whichmay be released and removed therefrom and a new cylinder placed therein to V take up the wear of the cylinder walls. 20

These objectsI accomplish with the device illustrated in the accompanying drawings in which similar letters .and numerals, of reference indicate like parts through the several views and as described in the specification forming a part of this application and pointed out in the appendedclaim.

In the drawings'in which I have shown the best and most preferred manner of building my invention. Figure 1 is a section'through a portion of a motor block showing my cylinniy cylinder. Figure 3 is a section longitudinally and diametrically through a modified form of constructing the cylinder showing the outer surface tapered. Figure 4 is another modification of constructing the cylinder. Figure 5 is a plan view of Figure 2. Figure 6 is a plan view of Figure 3 parts cut away. Figure 7 is a plan view of a modilication of Figure 3 parts cut away.

In the drawings I have shown the engine block as A in which my cylinders B are placed.v The engine block will be made with the cylinder hole 1 turned with the top of said hole enlarged at 2 to form a liange.- My cylin.

der Bis then threaded on eachendl thereof at 4 and 5 and a ring 6 is screwed down on to Y the threads 4 on the top end of the cylinder 5o and a threaded hole 7 is made through said .1929.. i Seraing., Y35.41.184# i i threaded -pjor'tion thereof, and aboltor screw 8 passed through' the hole 7 in thering fand ringandinto said cylinderwall, through y Y into the hole in the cylinder locking thering l Yand cylinder'together. y

Holes 9 are then bored eitherquarterlv or on eight sides of the cylinderV walland crescent-shaped holes 10 -a.recut inthe outer l Vperiphery o-f said ring 6. Stud bolts 11 are then passed down into the holes in theblock ywith the'heads thereof fitted intothefholes 10 inthe periphery ofvthe'ring 6.

This construction locks the ring and piston together and ylocksthe ring from rotation or longitudinal movement preventingthe cylind'er Afrofmmoving in rany direction whatso ever when. the engine is in operation.

'The head-of the motor;wlien it is placed over the top ofthe 'cylinder and the cylinder block will-then prevent the stud bolts .fromy comingout and willA Y. i v prevent the ring 6`y`from movement therein.'

` i lthe Yn'iodifiedf form sho-.wn inFigure-4 the lower endiof the cylinder is cut away at 12 forming 'a stepl 13 thereon. In this modijlied form .the ,engineblock will also be provided wi-t-h'a step thereon with the step 13 of Cil the cylinder adapted toreston the top side thereof.

Stud bolts 15 will then be passed into holes 14 and the cylinder block and will secure the cylinder within the block both from longitudinal movement and from rotation therein.

InV the modified form shown in Figure 3 the outer surface or the periphery of the cylinder which is shown as C is tap'ered'from top end 15 to the lower end 16. The wall of the cylinder block is forme-d with the same taper and the'cylinder is adapted to fit thereinto with stud bolts' 16 to secure the cylinder iin place.

It will be obvious that-the two modifica- Y tions shown in Figures 3 and 4 may have-their upperor top ends thereof externally threaded to be screwed either into the cylinder block itself or to have a ring similarV to the ring 6 (shown yin Figures 1 and 2) Vsecured thereonwith-the ring thensecured into the cylinder block similarly to' the manner sho-wn in' VFigure 1.V Also bosses 17, 18', 19, and 20 may' der and stud bolts passed Ythrough holes 21" be formed onithe outer Yperiphery of thetop end of either manner of building the cylinto 'secure the cylinder Within the cylinder block. The operation of my invention is as follows ' The 6 is threaded either onto the end i ll or of the cylinder B andthe screw 8 for operation.y n'

passed through the ring 6 into the cylinder This assembly is then' placed within the cylinder block and the stud bolts 11 screwed engine may then bei Should the cylinder Walls becomefworn,

the cylindervjmay be removed and reversed With the ringrG secured on the opppsite end of the cylinder and the vpiston reinserted therein. Thecylinder may: also be removed and rotated one-quarter, `one-hali, threequarters, jor completely around Within Athe cylinder block thereby changing the position ofthe sidewalls of .the cylinder and changing the portion which naturally receives the Y most gwear.

Y VHaving thus described invention I del sire to secure by Letters Patent and claim:

In a device of the classdeseribed the comy bination of a cylinder having both ends ex ternally threaded, a ring to be secured on one end of said cylindermeans to secure the ring j from rotation aroundl saidL cylinder, "and .means to secure said ringand cylinder Within the piston block. of an automobile engine.
